PENCIL.

SPECIFICATION forming part of Letters Patent No. 609,910, dated August.30, 1898.

Application filed Tune 14, 1897. erial No. 640,650. N m l- To all whomit may concern.-

Be it known that I, HERBERT H. SEAMAN,

a citizen of the United States, and a residentof New York, (Brooklyn,)in the county of Kings and State of New York, have invented certain newand useful Improvements in Penoils, of which the following is aspecification.

My present invention relates to that class i of pencils made thesubject-matter of Letters Patent No. 555,341, granted to me February 25,1896.

In making pencils according to the plan shown in said patent I have metwith considerable difficulty in the application of the covering orwrapping strip, and I have accordingly devised various ways ofovercoming the trouble thus experienced, one of which ways forms thesubject-matter of this application and another of a separate applicationfiled simultaneously with this. The Wrapping-strip or cover shown insaid patent is formed with a series of diagonal slots or perforations,which intersect the circular or peripheral grooves formed at the basesof the series of cones, so as to disclose the said grooves and thusassist the user to sever the Wrapper on the proper lines to enable thecones to be removed as required by the wearing out of the lead. The saidwrapper of my said patent is formed of a strip of paper or the likeequal in length to that of the pencil and of awidth slightly greaterthan is enough to wrap around the pencil, so that the longitudinal edgesof the strip overlap and are pasted one upon the other. In manufacturingpencils upon this plan I have found that the wrapping-stripmust be heldtaut while put on and that this distorts the wrapper or.

pnlls it out of shape, being unevenly weakened by the perforations, andas a consequence it is difficult and time-consuming to place the wrapperon properly or uniformly. Moreover, in gluing the wrapper by means of aglue brush or roller passing over the perforated strip some of the gluewill run through the perforations or slots and adhere to thewrapping-machine table and smear the outside of the wrapper. I haveendeavored to first glue or gum the paper and then perforate or slot it;but I found this impracticable, as the pieces out out adhere to the dieor cutter. Finding the perforated wrapper slow of application andobjectionable for the other reasons stated, I made numerous experimentsfor the purpose of discovering a more suitable or desirable mode ofapplying the wrapping-strip, which, it will be understood, must be soput on as to show where it must be broken or severed to enable theremoval or detachment of the successive cones.

In the present instance the means devised consists, essentially, in sospacing the edges of the wrapper as that a portion of each circulargroove formed by the junction of adjacent cones shall be uncovered andexposed to the eye, all as will be hereinafter more fully described, andparticularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is an enlarged side elevation ofa pencil embodying my present invention. Fig. 2 is an end elevationthereof, viewed from the point of the pencil. Fig. 3 is an enlarged sideelevation of a modification of my invention, and Fig. 4 is a furtherenlarged longitudinal central section of the form shown at Fig. 1.

In the several views the same part will be found designated by the samenumeral of reference.

1 designates the centrally-disposed continuous stick of lead or thelike, and 2 2 the series of individual nested conical sections ormembers. In this case I have shown an improved construction of conicalmember for the sake of convenience, but which I refrain from describingin detail, since it forms the subjectmatter of claims in my aforesaidcontemporaneous application. While showing this new construction ofconical member, it will be understood, however, that as far as mypresent improvement is concerned conicalmembers such as shown in my saidpatent may be employed in lieu thereof without departing from the spiritof my invention. Each conical member has a cylindrical collar 3, andbetween adjacent collars is a depression 4, extending circularly aboutthe pencil, there being one depression at the base of each conicalmember.

5 designates the wrapper, which is unperforated and which may be made ofpaper or other suitable material. At Figs. 1, 2, and

tpwf-cigzular depressions 4, as Well as the col lars 3;"but'of coursethe exposure of the depressions 4 is the main desideratum. By thusconstructing and applying the wrapper it will be seen that the user ofthe pencil may discern at a glance just where to apply the knife orother instrument in order to sever the wrapper circularly at the base ofthe next cone to be removed when it may be desired to uncover or projecta fresh portion of the lead. Referring now to Fig. 3, it will be seenthat the cover or wrapper, instead of being made of a length equal tothat of the pencil and of a width less than the circumference thereof,is made comparatively narrow in width and of considerably greater lengththan that of the pencil and is wrapped around the exterior of the conesin convolutions 0r spiral lines for practically the whole length of thepencil. This spiral or coiled wrapper 5 is so wound, as plainly seen atFig. 3, as that the adjacent edges of successive convolutions are laid aslight distance apart, thus producing spaces 7 and causing smallportions of the series of circular depressions 4 to be exposed along thewhole length of the pencil, thereby producing, as in Fig. 1, a structureby which successive cones may be removed with great nicety and facility.

What I claim as new, and desire to secure by Letters Patent, is

1. A pencil comprising a series of individual, nested, conical membersand having a series of depressions at the bases of the members, and awrapper covering only a portion of each said depressions and therebyexposing aportion of the same.

2. A pencil comprising a series of individual, nested, conical members,a series of circular depressions formed at the bases of said members,and awrapper or cover secured to said members and having its edgesspaced or separated so as to expose portions of said depressions.

3. A pencil comprising a series of individual, nested, conical members,a series of circular depressions formed at the bases thereof, and awrapper or cover of a length equal to said pencil and a width less thanthe circumference thereof and gummed or otherwise secured to saidconical members, so that its longitudinal edges are spaced or separatedand thereby expose portions of the said circular depressions.

Signed at New York city, in the county of New York and State of NewYork, this 11th day of June, A. D. 1897.
